JASPER T. TAYLOR, OF ORIENT, WASHINGTON.

SIARK-ARRESTER.

Application filed June 24, 1915.

To all whom it mag concern Be it known that I, JASPER T. TAYLOR, a citizen of the United States, residing at Orient, in the countyof Ferry and State of Washington, have invented a new and useful Spark-Arrester, of which the following is a specification.

This invention relates to spark arresters especially designed for use in connection with the smoke stacks of locomotives, one of the objects of the invention being to provide means whereby the products of combustion issuing from the stack of a locomotive will be directed downwardly and outwardly, thus to throw any hard unconsumed products downwardly away from the stack and out of the path of the current of the ascending gases.

A further object is to provide improved means for breaking up the current of ascending gases so that the separation of the unconsumed particles from said gases is thoroughly effected, the said particles dropping to the ground.

Another object is to provide means whereby the spark arrester can be adjusted upwardly and downwardly relative to the stack, thus enabling the same to passunder low bridges and through tunnels without in,

ury. 1 With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings :Figure 1 is a vertical longitudinal section through a portion of the smoke stack of a locomotive and showing the present improvements combined therewith. Fig. 2 is an enlarged section on line AB Fig. 1. Fig. 3 is a top plan View of the spark arrester.

Referring to the figures by characters of reference C designates a portion of a locomotive and D designates the upstanding smoke stack. In the present instance,- this stack is provided at each side with guide ribs 1 and slidably mounted on the stack is a frame 2 which is held against rotation by Specification of Letters Patent.

the ribs 1 and hasupwardly and outwardly diverging arms 8 integral therewith. Secured to these arms at intermediate points 1s a lower deflecting ring 4 which is flared upwardly and has a large opening 5 in the bottom thereof designed to receive products of combustion issuing from the stack.D. The arms 3 are curved inwardly and upwardly from this ring 4 and are secured at their upper ends to the dome-like member 6 provided with a central conical spreader 7 depending therefrom and the apex of which is in vertical alinement with the center of the stack D. Secured upon the arms 3 between the dome-like portion 6 and the ring 4 is a deflecting ring 8 flared clownwardly and spaced at its lower edge from the upper edge of the ring 4i and, at its upper edge, from the margin of the dome 6, said ring 8 overhanging the marginal portion of the dome 6 but being surrounded at its lower edge by the upper portion of the ring 1-. Connecting straps 9 may be secured to the dome 6 and the ring 8 for the purpose of holding the parts against accidental dis- 1 placement. Obviously any desired number of rings 8 may be used and the angle of inclination of the parts can be varied as well as the size of the rings, etc.

Connected to the upper portion of the stack is a pivot rod 9 on which is journaled a pulley 10. Secured to the frame 2 at each side thereof is a rack bar 11 and these rack bars are constantly engaged by gears 12 secured to a transverse shaft 13 journaled in brackets 14 depending from the stack D and outside of the path of frame 2. Shaft 13 has a pulley 15 secured to it and a flexible actuating device 16, which can be in the form of a light steel rope, is wrapped about this pulley and is extended upwardly over the pulley 10 and thence downwardly under pulleys 16 located adjacent the base of the stack D. The actuating element 16 is extended rearwardly to a suitable operating element, such as a Windlass 17 which may be rotated by means of a crank 18 or the like by the engineer or fireman.

It will be obvious that by rotating the Windlass 17 in one direction, the gears 12 can be rotated so as to slide the frame 2 upwardly upon the stack and, by reversing the movement of the connection 16, the frame 2 can be caused to move downwardly. Thus the spark arrester carried by the frame can be moved upwardly to active position and downwardly when, for example, it is desired to pass under a low bridge or through a tunnel.

When the products of combustion issue from the stack D, they will spread in all directions by the conical deflector? and the dome 6 and the unconsumed particles commingled therewith will be deflected downwardlv onto the ring 4 and thence inwardly off of the lower edge of the ring, these particles thus passing out of the path of the outflowing gases while the gases will escape through the spaces between the rings 4 and 8 and between the ring 8 and the dome 6.

Although a particular means has been shown for raising and lowering the spark arrester, it is to be understood that this means may be varied in order to produce the up and down movement of the spark arrester relative to the stack. For example, a ball and ratchet mechanism together with a rod for operating it might be employed in lieu of the cord shown and described, for

rotating the shaft 13.

What'is claimed is j l. The combination with the stack of a locomotive, of a spark arrester slidably' trio rings extending around and below the dome and forming outlets for gaseous products of combustion and deflectors for unconsumed particles.

2. The combination with the stack of a 3. The combination with the stack of a locomotive, of a frame-slidably mounted on the stack, upwardly extending arms carried by the frame, an upwardly flared ring carried by the arms, a dome supportedby the arms and above the stack, a depending conical deflector upon the dome, a deflecting ring interposed between the dome and first mentioned ring and extending over the mar:

ginal portion of the dome, sai'd rings and dome being spaced to form gas outlets,

means for sliding the frame upwardly and i T downwardlyupon the stack, and cooperating means upon the frame and stack for holding the spark arrester against rotation. in testimony that I claim the foregoing as my own, I havehereto afiixedmy signature in the presence of two witnesses.
